FAIRHOPE, Ala. -- Denard Robinson says he does not expect to return kicks or punts Saturday in the Senior Bowl.

The former Michigan quarterback, who hopes to make the NFL as a receiver and return man, wasn't among the North team's three punt or kick returners during Thursday's practice at Fairhope Municipal Stadium.

He did appear in one of the middle rows on the third kickoff return unit, which appeared to be the hands team.

Robinson has struggled in special teams roles this week, especially at punt returner. He fielded 19-of-26 attempts (73.1 percent) in the first three practices, but many of his catches came off a gun.

Off a live punter, Robinson was the North team's worst punt catcher.

"That’s the one thing I challenged him on," Oakland Raiders receivers coach Ted Gimore said. "I said once you get home, you have to work on that, because you have to be able to do that. He knows that."

Robinson says he plans to work with Michigan's kickers and punters when he returns to Ann Arbor, and hopes to pick up tips from Wolverines punt returners Jeremy Gallon and Drew Dileo.

"I know I need to get better," he said. "I think I did a little better (Wednesday), but I got to stick to it. It's hard for me to see the ball, but I'll get there. Just got to keep working."

Robinson was quiet at receiver during Thursday's practice, which was a light 90-minute workout in shorts. He caught 1-of-3 balls during red-zone drills, and was targeted just once during seven-on-seven and 11-on-11 drills.

He dropped the well-placed ball on a 5-yard dig route.

Robinson has drawn praise this week for his athleticism, which comes as little surprise for college football's all-time rushing leader at quarterback. He has used that athleticism to gain separation from more-experienced cornerbacks.

But he's struggled in most other facets of the position, especially with his routes, which remain raw.
